allow btMultiBody to not wakeup (for some RL experiments)
move deep_mimic motion files to data/motions folder, so we can use the args files unmodified.
expose minGraphicsUpdateTimeMs through PyBullet.connect(p.GUI, options="minGraphicsUpdateTimeMs=32000"), by default OpenGL rendering runs at 4000microseconds intervals.
allow a maximum of 128k objects
fix meshScale for PyBullet.createCollisionShape for custom mesh
expose Pybullet.setPhysicsEngineParameter(minimumSolverIslandSize=...), larger minimum batches group solver constraints together in the same island, to reduce calling overhead (even if they are not related)
this deepmimic is still very slow, due to slow mass matrix/inverse dynamics computation. once spherical motor drive is enabled, it should be fast(er)
move pd_controller_stable to pybullet_utils for easier re-use
add plane_transparent.urdf to pybullet_data
allow spacebar in keyboardEvents (Windows for now)
PyBullet: Implement a few more APIs of PhysX backend, resetJointState and setJointMotorControl2
allow useMaximalCoordinate=True for PhysX loadURDF (only for single rigid bodies, articulations require reduced coordinates at the moment)
Add inverse dynamics / mass matrix code from DeepMimic, thanks to Xue Bin (Jason) Peng
Add example how to use stable PD control for humanoid with spherical joints (see humanoidMotionCapture.py)
Fix related to TinyRenderer object transforms not updating when using collision filtering
See createMesh.py for an example.
The data has to fit in shared memory, hence the limit on Mac is lower than Windows and Linux:
#ifdef __APPLE__
#define B3_MAX_NUM_VERTICES 8192
#define B3_MAX_NUM_INDICES 32768
#else
#define B3_MAX_NUM_VERTICES 131072
#define B3_MAX_NUM_INDICES 524288
#endif
Using calculateInverseDynamics with zero target acceleration allows to compute the non-linear dynamics forces (coriolis/gyroscopic) and/or gravity force.
Add preparation for DeepMimic humanoid environment, replicating parts of https://github.com/xbpeng/DeepMimic
Loading humanoid.urdf and applying motion action: examples/pybullet/gym/pybullet_envs/mimic/humanoid.py
Loading MotionCapture data: examples/pybullet/gym/pybullet_envs/mimic/motion_capture_data.py
Little test: examples/pybullet/gym/pybullet_envs/mimic/humanoid_test.py
Expose this btMultiBodySphericalJointMotor through PyBullet.setJointMotorControlMultiDof
Expose PyBullet.getQuaternionSlerp
Improve PyBullet.setJointMotorControlMultiDof
Improve humanoidMotionCapture.py with slerp and using setJointMotorControlMultiDof
Expose btMultiBody::spatialTransform
Fix btMultiBody::setupPlanar from DeepMimic codebase
Add support for multidof joints in btMultiBody::compTreeLinkVelocities, thanks to DeepMimic codebase @xbpeng
See createObstacleCourse.py for an example use. At the moment a limit of 1024 vertices and 1024 indices.
Will be lifted once we implement the streaming version (soon).
b3InitUpdateVisualShape doesn't take textureUniqueId by default. new API b3UpdateVisualShapeTexture to change texture (-1 will clear texture)
PyBullet/BulletRobotics: allow to reset the textureUniqueId to -1, to clear a texture
PyBullet/BulletRobotics: save all texture handles
Support SDF loading through fileIO plugin.
Replace strcspn by C code (not crossplatform)
Add flag for loadURDF to use color from MTL file (instead from URDF link material)
pybullet.URDF_USE_MATERIAL_COLORS_FROM_MTL and pybullet.URDF_USE_MATERIAL_TRANSPARANCY_FROM_MTL
If parentObjectUniqueId provided, convert local from/to into world space coordinates
AddUserDebugLins: don't block when replacing an item
Fix examples/pybullet/examples/inverse_kinematics.py
PyBullet Allow OpenGL/EGL hardware to render segmentation mask. Use pybullet.ER_SEGMENTATION_MASK_OBJECT_AND_LINKINDEX or pybullet.ER_SEGMENTATION_MASK
PyBullet.removeBody fix indexing bug (use foundIndex, not i)
PyBullet bump up version to 2.2.3
Apply clang-format-all.sh using the _clang-format file through all the cpp/.h files.
make sure not to apply it to certain serialization structures, since some parser expects the * as part of the name, instead of type.
This commit contains no other changes aside from adding and applying clang-format-all.sh
allow to perform a getClosestPoints query with a collisionShape and world transform (position, orientation) that isn't part of the world.
(use createCollisionShape to create it)
add optional removeCollisionShape, for collision shapes only used in a query (and not used to create a body)
allow to perform a getClosestPoints query with a collisionShape and world transform (position, orientation) that isn't part of the world.
(use createCollisionShape to create it)
while (1):
stepSimulation()
pybullet.configureDebugVisualizer(pybullet.COV_ENABLE_SINGLE_STEP_RENDERING, 1)
disable single step using
pybullet.configureDebugVisualizer(pybullet.COV_ENABLE_SINGLE_STEP_RENDERING, 0)
Implement collisionFilterPlugin, use setCollisionFilterPair to enable or disable collision detection between specific pairs of objects.
Also, expose setCollisionFilterGroupMask as PyBullet API and in urdf using the tag <collision group="1" mask="2"/>.
See examples/pybullet/examples/collisionFilter.py for an example.
PyBullet default: Lower the warmstarting factor, for maximal coordinates rigid bodies for more stable simulation.
Add btCollisionWorld::refreshBroadphaseProxy to easier recreate the broadphase proxy without adding/removing objects to the world.
just use pybullet.loadPlugin("eglRendererPlugin") before loading/creating any objects.
use end/startRendering (swap buffers) before the rendering in the eglPlugin
add grpcPlugin, it can work in GUI, SHARED_MEMORY_SERVER, DIRECT and other modes.
example script to start server from pybullet:
import pybullet as p
p.connect(p.GUI)
#if statically linked plugin
id = p.loadPlugin("grpcPlugin")
#dynamics loading the plugin
#id = p.loadPlugin("E:/develop/bullet3/bin/pybullet_grpcPlugin_vs2010_x64_debug.dll", postFix="_grpcPlugin")
#start the GRPC server at hostname, port
if (id>=0):
p.executePluginCommand(id, "localhost:1234")
Only in DIRECT mode, since there is no 'ping' you need to call to handle RCPs:
numRPC = 10
while (1):
p.executePluginCommand(id, intArgs=[numRPC])
